hey i'm getting a map fooler that essencially portrays as the map sensor and tells the pcm to keep fueling reguardless to what the current boost levels may be. I havent tryed it out yet but as soon as it comes in the mail i will post the reactions that come from it. I'm currently running the evolution (edge) programer at the extreme mode and keep getting the ses light. I'm hopping that this map sensor fooler device will lie to my pcm and not send another excessive boost code or other codes that I continually retrive and delete. Quick question? One of the codes I get is 0237 and from what my programer tells me it say exactly this "tubo boost circuit A low input". could that be a bad map sensor or something else?
